Distinguish between a producer, a consumer and a decomposer.<\/p>\n\n\n\n\n
and convert that light energy into chemical bond energy. such as
some bacteria, protists, and all plants
consumer: organisms that feed on already-stored food
decomposer: bacteria and fungi recycle the dead molecules
throughout the bioshpere.
Distinguish between a hypothesis and a prediction. – ANSWERhypothesis: testable explanation of a natural phenomenon.
prediction: statement based on hypothesis about a condition that
should exit if the hypothesis is correct.
What is meant by the phrase potentially falsifiable hypothesis? –
ANSWER- a hypothesis can be proven that is false
Define the term control group and explain the value of a control
group in an experiment. – ANSWER- Group of individuals<\/li>\n<\/ul>\n\n\n\n
identical to an experimental group except for the independent
variable under investigation
To provide a basis of comparison to the experimental group
Define the term theory and explain the point in which a
hypothesis becomes a theory. – ANSWER- Suppose a
hypothesis stands even after years of tests.
It is consistent with all data ever gathered, and it has helped us
make successful predictions about other phenomena.
Explain how electron configuration influences the chemical
properties of an atom. – ANSWER- Each cloud can hold a
determinant number of electrons. When the electron number
changes, ions are formed. The number of electrons influences
the bonding between atoms.
hydrogen bond – ANSWER- The electron from the hydrogen
spends most of its time around the oxygen atom creating a
partial positive charge on each hydrogen. The presence of
additional electrons makes the oxygen partially negative.
covalent bond – ANSWER- two atoms share a pair of electrons,
so that each atom’s vacancy
becomes partially filled<\/p>\n\n\n\n
ionic bond – ANSWER- Type of chemical bond in which a
strong mutual attraction links ions of opposite charge.

that supports all life. – ANSWER- 1. an excellent solvent<\/p>\n\n\n\n
